semantic segmetation
semantic segmetation use case example
Important
For semantic segmentation dataset, tags value under visionai format is mandatory. Thetag works as the classes information of binary attributes of RLE data in objects under frame.
To describe a semantic segmentation dataset with one camera sensor:
sensor: camera (#camera1)
ontology
background
person
bicycle
car
motorcycle
airplane
bus
train
truck
boat
trafficlight
